Aminothiazole Compounds as Inhibitors of CTPS1

ABSTRACT

Compounds of formula (I): (I) and related aspects.

FIELD OF THE INVENTION

The invention relates to novel aminothiazole compounds, processes for the manufacture of such compounds, related intermediates, compositions comprising such compounds and the use of such compounds as cytidine triphosphate synthase 1 inhibitors, particularly in the treatment or prophylaxis of disorders associated with cell proliferation.

BACKGROUND OF THE INVENTION

Nucleotides are a key building block for cellular metabolic processes such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) synthesis. There are two classes of nucleotides, that contain either purine or pyrimidine bases, both of which are important for metabolic processes.

Based on this, many therapies have been developed to target different aspects of nucleotide synthesis, with some inhibiting generation of purine nucleotides and some pyrimidine nucleotides, or both.

The pyrimidine nucleotide cytidine 5′ triphosphate (CTP) is a precursor required not just for the metabolism of DNA and RNA but also phospholipids and sialyation of proteins. CTP originates from two sources: a salvage pathway and a de novo synthesis pathway that depends on two enzymes, the CTP synthases (or synthetases) 1 and 2 (CTPS1 and CTPS2) (Evans and Guy 2004; Higgins, et al. 2007; Ostrander, et al. 1998).

CTPS1 and CTPS2 catalyse the conversion of uridine triphosphate (UTP) and glutamine into cytidine triphosphate (CTP) and L-glutamate:

Both enzymes have two domains, an N-terminal synthetase domain and a C-terminal glutaminase domain (Kursula, et al. 2006). The synthetase domain transfers a phosphate from adenosine triphosphate (ATP) to the 4-position of UTP to create an activated intermediate, 4-phospho-UTP. The glutaminase domain generates ammonia from glutamine, via a covalent thioester intermediate with a conserved active site cysteine, generating glutamate. This ammonium is transferred from the glutaminase domain to the synthetase domain via a tunnel or can be derived from external ammonium. This ammonium is then used by the synthetase domain to generate CTP from the 4-phospho-UTP (Lieberman, 1956).

Although CTPS exists as two isozymes in humans and other eukaryotic organisms, CTPS1 and CTPS2, functional differences between the two isozymes are not yet fully elucidated (van Kuilenburg, et al. 2000).

The immune system provides protection from infections and has therefore evolved to rapidly respond to the wide variety of pathogens that the individual may be exposed to. This response can take many forms, but the expansion and differentiation of immune populations is a critical element and is hence closely linked to rapid cell proliferation. Within this, CTP synthase activity appears to play an important role in DNA synthesis and the rapid expansion of lymphocytes following activation (Fairbanks, et al. 1995; van den Berg, et al. 1995).

Strong clinical validation that CTPS1 is the critical enzyme in human lymphocyte proliferation came with the identification of a loss-of-function homozygous mutation (rs145092287) in this enzyme that causes a distinct and life-threatening immunodeficiency, characterized by an impaired capacity of activated T- and B-cells to proliferate in response to antigen receptor-mediated activation. Activated CTPS1-deficient cells were shown to have decreased levels of CTP. Normal T-cell proliferation was restored in CTPS1-deficient cells by expressing wild-type CTPS1 or by addition of exogenous CTP or its nucleoside precursor, cytidine. CTPS1 expression was found to be low in resting lymphocytes, but rapidly upregulated following activation of these cells. Expression of CTPS1 in other tissues was generally low. CTPS2 seems to be ubiquitously expressed in a range of cells and tissues but at low levels, and the failure of CTPS2, which is still intact in the patients, to compensate for the mutated CTPS1, supports CTPS1 being the critical enzyme for the immune populations affected in the patients (Martin, et al. 2014).

Overall, these findings suggest that CTPS1 is a critical enzyme necessary to meet the demands for the supply of CTP required by several important immune cell populations.

Normally the immune response is tightly regulated to ensure protection from infection, whilst controlling any response targeting host tissues. In certain situations, the control of this process is not effective, leading to immune-mediated pathology. A wide range of human diseases are thought to be due to such inappropriate responses mediated by different elements of the immune system.

Given the role that cell populations, such as T and B lymphocytes, are thought to play in a wide range of autoimmune and other diseases, CTPS1 represents a target for a new class of immunosuppressive agents. Inhibition of CTPS1 therefore provides a novel approach to the inhibition of activated lymphocytes and selected other immune cell populations such as Natural Killer cells, Mucosal-Associated Invariant T (MAIT) and Invariant Natural Killer T cells, highlighted by the phenotype of the human mutation patients (Martin, et al. 2014).

Cancer can affect multiple cell types and tissues but the underlying cause is a breakdown in the control of cell division. This process is highly complex, requiring careful coordination of multiple pathways, many of which remain to be fully characterised. Cell division requires the effective replication of the cell's DNA and other constituents. Interfering with a cell's ability to replicate by targeting nucleic acid synthesis has been a core approach in cancer therapy for many years. Examples of therapies acting in this way are 6-thioguanine, 6-mecaptopurine, 5-fluorouracil, cytarabine, gemcitabine and pemetrexed.

As indicated above, pathways involved in providing the key building blocks for nucleic acid replication are the purine and pyrimidine synthesis pathways, and pyrimidine biosynthesis has been observed to be up-regulated in tumors and neoplastic cells.

CTPS activity is upregulated in a range of tumour types of both haematological and non-haematological origin, although heterogeneity is observed among patients. Linkages have also been made between high enzyme levels and resistance to chemotherapeutic agents.

Currently, the precise role that CTPS1 and CTPS2 may play in cancer is not completely clear. Several non-selective CTPS inhibitors have been developed for oncology indications up to phase I/II clinical trials, but were stopped due to toxicity and efficacy issues.

Most of the developed inhibitors are nucleoside-analogue prodrugs (3-deazauridine, CPEC, carbodine), which are converted to the active triphosphorylated metabolite by the kinases involved in pyrimidine biosynthesis: uridine/cytidine kinase, nucleoside monophosphate-kinase (NMP-kinase) and nucleoside diphosphatekinase (NDP-kinase). The remaining inhibitors (acivicin, DON) are reactive analogues of glutamine, which irreversibly inhibit the glutaminase domain of CTPS. Gemcitibine is also reported to have some inhibitory activity against CTPS (McClusky et al., 2016).

CTPS therefore appears to be an important target in the cancer field. The nature of all of the above compounds is such that effects on other pathways are likely to contribute to the efficacy they show in inhibiting tumours.

Selective CTPS inhibitors therefore offer an attractive alternative approach for the treatment of tumours. Compounds with different potencies against CTPS1 and CTPS2 may offer important opportunities to target different tumours depending upon their relative dependence on these enzymes.

CTPS1 has also been suggested to play a role in vascular smooth muscle cell proliferation following vascular injury or surgery (Tang et al., 2013).

As far as is known to date, no selective CTPS1 inhibitors have been developed. Recently, the CTPS1 selective inhibitory peptide CTpep-3 has been identified. The inhibitory effects of CTpep-3 however, were seen in cell free assays but not in the cellular context. This was not unexpected though, since the peptide is unlikely to enter the cell and hence is not easily developable as a therapeutic (Sakamoto, et al. 2017).

In summary, the available information and data strongly suggest that inhibitors of CTPS1 will reduce the proliferation of a number of immune and cancer cell populations, with the potential for an effect on other selected cell types such as vascular smooth muscle cells as well. Inhibitors of CTPS1 may therefore be expected to have utility for treatment or prophylaxis in a wide range of indications where the pathology is driven by these populations.

CTPS1 inhibitors represent a novel approach for inhibiting selected components of the immune system in various tissues, and the related pathologies or pathological conditions such as, in general terms, rejection of transplanted cells and tissues, Graft-related diseases or disorders, allergies and autoimmune diseases. In addition, CTPS1 inhibitors offer therapeutic potential in a range of cancer indications and in enhancing recovery from vascular injury or surgery and reducing morbidity and mortality associated with neointima and restenosis.

The compounds of the invention may be provided in the form of a pharmaceutically acceptable salt and/or solvate thereof and/or derivative thereof. In particular, the compound of formula (I) may be provided in the form of a pharmaceutically acceptable salt and/or solvate, such as a pharmaceutically acceptable salt.

Compounds of the invention of particular interest are those demonstrating an IC₅₀ of 1 uM or lower, especially 100 nM or lower, in respect of CTPS1 enzyme, using the methods of the examples (or comparable methods).

Compounds of the invention of particular interest are those demonstrating a selectivity for CTPS1 over CTPS2 of 2-30 fold, suitably >30-60 fold or more suitably >60 fold, using the methods of the examples (or comparable methods).

It will be appreciated that for use in medicine the salts of the compounds of formula (I) should be pharmaceutically acceptable. Non-pharmaceutically acceptable salts of the compounds of formula (I) may be of use in other contexts such as during preparation of the compounds of formula (I). Suitable pharmaceutically acceptable salts will be apparent to those skilled in the art. Pharmaceutically acceptable salts include those described by Berge et al. (1977). Such pharmaceutically acceptable salts include acid and base addition salts. Pharmaceutically acceptable acid additional salts may be formed with inorganic acids e.g. hydrochloric, hydrobromic, sulphuric, nitric or phosphoric acid and organic acids e.g. succinic, maleic, acetic, fumaric, citric, tartaric, benzoic, p-toluenesulfonic, methanesulfonic or naphthalenesulfonic acid.

Other salts e.g. oxalates or formates, may be used, for example in the isolation of compounds of formula (I) and are included within the scope of this invention.

Certain compounds of formula (I) may form acid or base addition salts with one or more equivalents of the acid or base. The present invention includes within its scope all possible stoichiometric and non-stoichiometric forms.

The compounds of formula (I) may be prepared in crystalline or non-crystalline form and, if crystalline, may optionally be solvated, e.g. as the hydrate. This invention includes within its scope stoichiometric solvates (e.g. hydrates) as well as compounds containing variable amounts of solvent (e.g. water).

It will be understood that the invention includes pharmaceutically acceptable derivatives of compounds of formula (I) and that these are included within the scope of the invention.

As used herein “pharmaceutically acceptable derivative” includes any pharmaceutically acceptable prodrug such as an ester or salt of such ester of a compound of formula (I) which, upon administration to the recipient is capable of providing (directly or indirectly) a compound of formula (I) or an active metabolite or residue thereof.

It is to be understood that the present invention encompasses all isomers of formula (I) and their pharmaceutically acceptable derivatives, including all geometric, tautomeric and optical forms, and mixtures thereof (e.g. racemic mixtures). Where additional chiral centres are present in compounds of formula (I), the present invention includes within its scope all possible diastereoisomers, including mixtures thereof. The different isomeric forms may be separated or resolved one from the other by conventional methods, or any given isomer may be obtained by conventional synthetic methods or by stereospecific or asymmetric syntheses.

The present disclosure includes all isotopic forms of the compounds of the invention provided herein, whether in a form (i) wherein all atoms of a given atomic number have a mass number (or mixture of mass numbers) which predominates in nature (referred to herein as the “natural isotopic form”) or (ii) wherein one or more atoms are replaced by atoms having the same atomic number, but a mass number different from the mass number of atoms which predominates in nature (referred to herein as an “unnatural variant isotopic form”). It is understood that an atom may naturally exists as a mixture of mass numbers. The term “unnatural variant isotopic form” also includes embodiments in which the proportion of an atom of given atomic number having a mass number found less commonly in nature (referred to herein as an “uncommon isotope”) has been increased relative to that which is naturally occurring e.g. to the level of >20%, >50%, >75%, >90%, >95% or >99% by number of the atoms of that atomic number (the latter embodiment referred to as an “isotopically enriched variant form”). The term “unnatural variant isotopic form” also includes embodiments in which the proportion of an uncommon isotope has been reduced relative to that which is naturally occurring. Isotopic forms may include radioactive forms (i.e. they incorporate radioisotopes) and non-radioactive forms. Radioactive forms will typically be isotopically enriched variant forms.

An unnatural variant isotopic form of a compound may thus contain one or more artificial or uncommon isotopes such as deuterium (²H or D), carbon-11 (¹¹C), carbon-13 (¹³C), carbon-14 (¹⁴C), nitrogen-13 (¹³N), nitrogen-15 (¹⁵N), oxygen-15 (¹⁵O), oxygen-17 (¹⁷O), oxygen-18 (¹⁸O), phosphorus-32 (³²P), sulphur-35 (³⁵S), chlorine-36 (³⁶Cl), chlorine-37 (³⁶Cl), fluorine-18 (¹⁸F) iodine-123 (¹²³I), iodine-125 (¹²⁵I) in one or more atoms or may contain an increased proportion of said isotopes as compared with the proportion that predominates in nature in one or more atoms.

Unnatural variant isotopic forms comprising radioisotopes may, for example, be used for drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, i.e. ³H, and carbon-14, i.e. ¹⁴C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection. Unnatural variant isotopic forms which incorporate deuterium i.e ²H or D may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. Further, unnatural variant isotopic forms may be prepared which incorporate positron emitting isotopes, such as ¹¹C, ¹⁸F, ¹⁵O and ¹³N, and would be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy.

In one embodiment, the compounds of the invention are provided in a natural isotopic form.

In one embodiment, the compounds of the invention are provided in an unnatural variant isotopic form. In a specific embodiment, the unnatural variant isotopic form is a form in which deuterium (i.e. ²H or D) is incorporated where hydrogen is specified in the chemical structure in one or more atoms of a compound of the invention. In one embodiment, the atoms of the compounds of the invention are in an isotopic form which is not radioactive. In one embodiment, one or more atoms of the compounds of the invention are in an isotopic form which is radioactive. Suitably radioactive isotopes are stable isotopes. Suitably the unnatural variant isotopic form is a pharmaceutically acceptable form.

In one embodiment, a compound of the invention is provided whereby a single atom of the compound exists in an unnatural variant isotopic form. In another embodiment, a compound of the invention is provided whereby two or more atoms exist in an unnatural variant isotopic form.

Unnatural isotopic variant forms can generally be prepared by conventional techniques known to those skilled in the art or by processes described herein e.g. processes analogous to those described in the accompanying Examples for preparing natural isotopic forms. Thus, unnatural isotopic variant forms could be prepared by using appropriate isotopically variant (or labelled) reagents in place of the normal reagents employed in the Examples. Since the compounds of formula (I) are intended for use in pharmaceutical compositions it will readily be understood that they are each preferably provided in substantially pure form, for example at least 60% pure, more suitably at least 75% pure and preferably at least 85%, especially at least 98% pure (% are on a weight for weight basis). Impure preparations of the compounds may be used for preparing the more pure forms used in the pharmaceutical compositions.

In general, the compounds of formula (I) may be made according to the organic synthesis techniques known to those skilled in this field, as well as by the representative methods set forth below, those in the Examples, and modifications thereof.

General Routes:

Generic routes by which compound examples of the invention may be conveniently prepared are summarised below.

Compounds of general formula (I), where R₁, R₂, R₃, R₄, R₅, R₆, R₁₀, R₁₁, R₁₂, R₁₃, Ar1 and Ar2 are defined above, may be synthesised by the general scheme (Scheme 1). Ketoesters of formula (VII) may be prepared by alkylation of an unsubstituted ketoester, which is well established in the literature with many simple derivatives being commercially available.

Intermediates of formula (V) are readily prepared from ketoesters of formula (VII) using a two step procedure. Firstly, bromination using bromine or pyrimidium tribromide can afford the alpha bromoketone ester. This intermediate may be isolated but is routinely used directly without characterisation or purification in the subsequent step. Thiourea (VIII) may be added to form thiazoles of the formula (V) via cyclisation. Such reactions may be subject to gentle heating to, for example, 40° C.

The compound intermediates of formula (IV) can be obtained by sulfonylation of amines of formula (V) with a suitable sulfonyl chloride (VI) in pyridine. Such reactions may be subject to gentle heating to, for example, 30-60° C.

The alkyl esters of formula (IV) may be conveniently hydrolysed by exposure to a suitable inorganic base, for example lithium hydroxide, in an aqueous mixture of aprotic and protic solvents, such as THF:methanol:water. Such reactions may be subject to gentle heating to, for example, 30-50° C.

Compounds of formula (I) may be obtained by a general process whereby a carboxylic acid precursor (II), or a suitably protected derivative thereof, is reacted with an activating agent, to generate a reactive, electrophilic carboxylic acid derivative, followed by subsequent reaction with an amine of formula (III), or a suitably protected derivative thereof. It will be understood by persons skilled in the art that, in some instances, the activated carboxylic acid derivative, such as an acid chloride, may be isolated or in other cases may be a transient intermediate that is not isolated, but generated in situ and used directly. Reagents suitable for the activation of the carboxylate group include carbonyl diimidazole, 1-chloro-N,N,2-trimethylprop-1-en-1-amine (Ghosez reagent) and a wide selection of peptide coupling agents such as 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium 3-oxid hexafluoro-phosphate (HATU) and the like. Such reactions are conveniently carried out in a non-polar, aprotic solvent, such as DCM at or below ambient temperature.

If R₃═H in compounds of the general formula (I), substitution can be undertaken using a halogenating reagent, such as N-chlorosuccinimide, in an organic solvent such as MeCN to generate compounds of the general formula (I) wherein R₃═Cl.

Compounds of formula (I) may be obtained by a general process whereby a carboxylic acid precursor (II), or a suitably protected derivative thereof, is reacted with an activating agent, to generate a reactive, electrophilic carboxylic acid derivative, followed by subsequent reaction with an amine of formula (IX). Intermediates of formula (X) are then converted to a compound of the invention of general formula (I) by coupling under Suzuki conditions with an aromatic halide or boronate of general formula (XI), of which X is defined above and represents usually a bromide, a dihydroxyboryl or dialkyloxyboryl group, usually a 4,4,5,5-tetramethyl-1,3,3,2-dioxaborolan-2-yl group. The couplings according to the Suzuki method are performed, for example, by heating in the presence of a catalyst such as bis(diphenylphosphino)ferrocene]dichloropalladium(II) and an inorganic base such as potassium carbonate in a solvent mixture of dioxane and water. It will be understood by persons skilled in the art that many catalysts and conditions can be employed for such couplings.

Intermediates of formula (III) where Ar2 is an unsubstituted or substituted 3-pyridyl ring, may be synthesised by coupling under Suzuki conditions of a boronate of general formula (XI), of which R¹² and R¹³ are defined above and Z represents a dihydroxyboryl or dialkyloxyboryl group, usually a 4,4,5,5-tetramethyl-1,3,3,2-dioxaborolan-2-yl group, to a substituted pyridine of formula (IX) of which R¹⁰ and R¹¹ are defined above and where X denotes a halide. The couplings according to the Suzuki method are performed, for example, by heating in the presence of a catalyst such as [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane and an inorganic base such as potassium carbonate in a solvent mixture of 1,4-dioxane and water.

Intermediates of formula (III) where Ar2 is an unsubstituted or substituted 2-pyrazine ring, may be synthesised by coupling under Suzuki conditions of an aromatic halide of general formula (XI), of which R¹² and R¹³ are defined above and Z represents a halide, to a boronate of general formula (IX) of which R¹⁰ and R¹¹ are defined above and where X denotes a dihydroxyboryl or dialkyloxyboryl group, usually a 4,4,5,5-tetramethyl-1,3,3,2-dioxaborolan-2-yl group. The couplings according to the Suzuki method are performed, for example, by heating in the presence of a catalyst such as tetrakis(triphenylphosphine)palladium or [1,1′-bis(diphenylphosphino) ferrocene]dichloropalladium(II) and an inorganic base such as potassium carbonate in a solvent mixture of dioxane and water.

The compound intermediates of formula (I) where Ar1 is a 2-amino pyrimidine, can be obtained by activating the acid (II) with a suitable activating agent, to generate a reactive, electrophilic carboxylic acid derivative, followed by subsequent reaction with an ammonia source such as ammonium hydroxide. The primary amide (XII) can then be coupled with a 2-chloropyrimidine derivative (XIII) using a palladium catalyst such as Pd 177 (Xantphos precatalyst) and inorganic base, for example cesium carbonate in 1,4-dioxane to yield compounds of the general formula (I). It will be understood by persons skilled in the art that traditional coupling conditions directly from an electrophilic carboxylic acid derivative and 2-aminopyrimidine derivative are difficult due to the unreactive nature of the nucleophile.

In general and as illustrated in Scheme 6, the 2-(2-(alkylsulfonamido)thiazol-4-yl) amide derivatives of general formula (I) in which R₁, R₆, Ar1 and Ar2 are defined above may be prepared in several steps, starting from methyl 2-(2-aminothiazol-4-yl)acetate. Intermediates of formula (XVI) can be formed by sequential protection of the amine (V) with suitable N-protecting groups such as Boc and PMB protecting groups. Addition of a base, such as 1,8-diazabicyclo[5.4.0]undec-7-ene, and tosyl azide leads to the selective introduction of the diazo functional group on the alpha-position relative to the ester to yield intermediates of formula (XIV). Under rhodium catalysis and in the presence of a nucleophilic source, such as methanol, followed by deprotection of both protecting groups at elevated temperatures, derivatives of formula (V) may be prepared. The compound intermediates of formula (IV) can be obtained by sulfonylation of amines of formula (V) with a suitable sulfonyl chloride (VI) in pyridine. Such reactions may be subject to gentle heating to, for example, 30-50° C. The alkyl esters of formula (IV) may be conveniently converted to compounds of formula (I) according to synthetic steps reported in Scheme 1.

The difluoro intermediate of formula (XV) may be prepared in two steps by firstly Boc protection using Boc-anhydride in a polar solvent such as dichloroethane, followed by utilisation of a fluorinating agent such as bis(2-methoxyethyl)aminosulfur trifluoride. These fluorination reactions are, for example, performed at RT and in a solvent such as toluene. The following deprotection to yield the free aminothiazole (V) is performed, for example, by exposure to acid in an organic solvent, such as HCl in 1,4-dioxane. The compound intermediates of formula (IV) can be obtained by sulfonylation of amines of formula (V) with a suitable sulfonyl chloride (VI) in pyridine. Such reactions may be subject to gentle heating to, for example, 30-50° C. The alkyl esters of formula (IV) may be conveniently converted to compounds of formula (I) according to synthetic steps reported in Scheme 1.

Compound of general formula (XVII) may be prepared by conversion of a suitable 2-(2-aminothiazol-4-yl)acetate derivative, such as a methyl or ethyl derivative, by a Sandmeyer type reaction using an organic nitrite, such as n-butylnitrite, in the presence of a halide source, such as Cu(I)Br in acetonitrile. Such reactions can be undertaken at temperatures of RT to 60° C. Introduction of R₄/R₅ can be undertaken by two alternative methods at this stage. Firstly, alkylation of compounds of general formula (XVII) can be undertaken by addition of a suitable base, for example, LiHMDS, together with an alkylating agent, such as iodomethane which results in dialkylation alpha to the ester moiety to yield compounds of formula (XVIII), where R₄═R₅=Me. Secondly, diazotisation of compounds of general formula (XVII) with the use of an diazo transfer reagent, such as 4-acetamidobenzenesulfonyl azide, under basic conditions, followed by treatment with rhodium and subsequent insertion of the corresponding nucleophile, such as isopropyl alcohol, gives intermediates of general formula (XVIII) where R₄=Oisopropoxy and R₅ ═H.

Introduction of the sulfonamide group in the preparation of compounds of formula (IV) may be achieved by an Ullmann coupling reaction i.e. Cu mediated coupling conditions using amines of formula (XXIV) and a copper catalyst, such as Cu(I)I, in the presence of an inorganic base, potassium carbonate, and a diamine ligand in dioxane. Such reactions are typically carried out at elevated temperatures such as 80° C. Alternatively, conversion of compounds of formula (XVIII) to (IV) can be achieved via a palladium mediated coupling, for example using a catalyst such as [t-BuXPhos Pd(allyl)]OTf and substituted sulfonamide nucleophile (XXIV), in the presence of an inorganic base, for example potassium carbonate to form compounds of formula (IV). Palladium mediatiated coupling conditions are particularly useful when R₄ and R₅ together with the carbon atom to which they are attached form a 5- or 6-membered heterocycloalkyl, such as a tetrahydropyranyl. The alkyl esters of formula (IV) may be conveniently converted to compounds of formula (I) according to synthetic steps reported in Scheme 1.

Compounds of general formula (I), where R₁, R₃, R₆, R₁₃, Ar1 and Ar2 are defined above, may be synthesised by the general scheme shown above. The compound intermediates of formula (IV) can be obtained by sulfonylation of amines of formula (V) with a suitable sulfonyl chloride (VI) in pyridine. Such reactions may be subject to gentle heating to, for example, 30-60° C. Reaction of ketone (IV) with O-methylhydroxylamine in the presence of trimethylamine yields the methoxyiminoacetate intermediate (XX). This can be reduced by addition of zinc in the presence of formaldehyde at temperatures such as 0° C. Ethyl 2-amino-2-(2-(cyclopropanesulfonamido)thiazol-4-yl)acetate is not formally isolated but after ion exchange chromatography purification may be protected with di-tert-butyl dicarbonate to afford intermediate (XXI). To obtain compound (XXII) intermediate (XXI) can be subjected to hydrolysis using an inorganic base such as LiOH. Compound of formula (XXIII) can be obtained by reaction of acid (XXII) with an activating reagent such as HATU followed by addition in situ of a chosen amine of formula (III). Finally compound (XXIII) can be deprotected using an acid such as TFA to yield final compound (I).

Intermediate compounds of formula (III) may be obtained by a two-step, one pot process whereby an aryl bromide precursor (IX) is reacted with bis(pinacolato)diborane under Suzuki conditions using a catalyst such as bis(diphenylphosphino)ferrocene]dichloropalladium(II) and an inorganic base such as potassium carbonate, in a solvent mixture of dioxane and water. The 4,4,5,5-tetramethyl-1,3,3,2-dioxaborolan-2-yl intermediate is not formally isolated but is then reacted directly by a second Suzuki reaction with an aromatic halide of general formula (XI) using the conditions described above.

Compounds of formula (I) may be obtained by a two-step, one pot process whereby an aryl halide precursor (X) is reacted with bis(pinacolato)diborane under Suzuki conditions using a catalyst such as bis(diphenylphosphino)ferrocene]dichloropalladium(II) and an inorganic base such as potassium carbonate, in a solvent mixture of dioxane and water. The 4,4,5,5-tetramethyl-1,3,3,2-dioxaborolan-2-yl intermediate is then reacted directly by a second Suzuki reaction with an aromatic halide of general formula (XI) using the conditions described above.

Compounds of general formula (I) when R₄ and R₅ together with the carbon atom to which they are attached form a C₃₋₆heterocycloalkyl ring may be prepared by bis-alkylation of compounds of general formula (XVII) which can be undertaken by the addition of a suitable base, for example, NaOH, together with a bis-alkylating agent, such as 1-bromo-2-(2-bromoethoxy)ethane. Palladium catalysed sulfonamidation of intermediate (XVIII) may be achieved using a catalytic system using [Pd(allyl)Cl]₂ and a phosphine mono-dentate ligand such as t-BuXPhos in the presence of a primary sulphonamide (XXIV) to obtain compounds of the formula (IV). Such reactions are typically carried out at elevated temperatures such as 90° C. The alkyl esters of formula (IV) may be conveniently converted to compounds of formula (I) according to synthetic steps reported in Scheme 1.

Acylation of compounds of formula (XXV) in the presence of a         strong base such as LDA followed by a quench with an —OAc source         such as EtOAc provides compounds of formula (XXVI). Compounds of         formula (XXVII) can be made from (XXVI) following addition of         bromine and quench with a suitable thiourea, before a coupling         with sulfonyl chlorides of formula (VI) to give compounds of         formula (XXVIII).

The invention also provides the use of a pharmaceutical composition comprising a compound of formula (I), or a pharmaceutically acceptable salt and/or solvate thereof (e.g. salt) and/or derivative thereof, in the manufacture of a medicament for the treatment or prophylaxis of a disease or disorder as described herein.

The compounds of formula (I) or their pharmaceutically acceptable salts and/or solvates and/or derivatives thereof may be administered by any convenient method, e.g. by oral, parenteral, buccal, sublingual, nasal, rectal or transdermal administration, and the pharmaceutical compositions adapted accordingly.

The compounds of formula (I) or their pharmaceutically acceptable salts and/or solvates and/or derivatives thereof may be administered topically for example to the eye, gut or skin. Thus, in an embodiment there is provided a pharmaceutical composition comprising a compound of the invention optionally in combination with one or more topically acceptable diluents or carriers.

A pharmaceutical composition of the invention may be delivered topically to the skin. Compositions suitable for transdermal administration include ointments, gels and patches. Such a pharmaceutical composition may also suitably be in the form of a cream, lotion, foam, powder, paste or tincture.

The pharmaceutical composition may suitably include vitamin D3 analogues (e.g calcipotriol and maxacalcitol), steroids (e.g. fluticasone propionate, betamethasone valerate and clobetasol propionate), retinoids (e.g. tazarotene), coal tar and dithranol. Topical medicaments are often used in combination with each other (e.g. a vitamin D3 and a steroid) or with further agents such as salicylic acid.

A pharmaceutical composition of the invention may be delivered topically to the eye. Such a pharmaceutical composition may suitably be in the form of eye drops or an ointment.

A pharmaceutical composition of the invention may be delivered topically to the gut. Such a pharmaceutical composition may suitably be delivered orally, such as in the form of a tablet or a capsule, or rectally, such as in the form of a suppository.

Suitably, delayed release formulations are in the form of a capsule.

The compounds of formula (I) or their pharmaceutically acceptable salts and/or solvates and/or derivatives thereof which are active when given orally can be formulated as liquids or solids, e.g. as syrups, suspensions, emulsions, tablets, capsules or lozenges.

A liquid formulation will generally consist of a suspension or solution of the active ingredient (such as a compound of formula (I) or a pharmaceutically acceptable salt and/or solvate (e.g. salt) and/or derivative thereof) in a suitable liquid carrier(s) e.g. an aqueous solvent such as water, ethanol or glycerine, or a non-aqueous solvent, such as polyethylene glycol or an oil. The formulation may also contain a suspending agent, preservative, flavouring and/or colouring agent.

A composition in the form of a tablet can be prepared using any suitable pharmaceutical carrier(s) routinely used for preparing solid formulations, such as magnesium stearate, starch, lactose, sucrose and cellulose.

A composition in the form of a capsule can be prepared using routine encapsulation procedures, e.g. pellets containing the active ingredient (such as a compound of formula (I) or a pharmaceutically acceptable salt and/or solvate (e.g. salt) and/or derivative thereof) can be prepared using standard carriers and then filled into a hard gelatin capsule; alternatively a dispersion or suspension can be prepared using any suitable pharmaceutical carrier(s), e.g. aqueous gums, celluloses, silicates or oils and the dispersion or suspension then filled into a soft gelatin capsule.

Typical parenteral compositions consist of a solution or suspension of the active ingredient (such as a compound of formula (I) or a pharmaceutically acceptable salt and/or solvate (e.g. salt) and/or derivative thereof) in a sterile aqueous carrier or parenterally acceptable oil, e.g. polyethylene glycol, polyvinyl pyrrolidone, lecithin, arachis oil or sesame oil. Alternatively, the solution can be lyophilised and then reconstituted with a suitable solvent just prior to administration.

Compositions for nasal administration may conveniently be formulated as aerosols, drops, gels and powders. Aerosol formulations typically comprise a solution or fine suspension of the active ingredient in a pharmaceutically acceptable aqueous or non-aqueous solvent and are usually presented in single or multidose quantities in sterile form in a sealed container which can take the form of a cartridge or refill for use with an atomising device. Alternatively the sealed container may be a disposable dispensing device such as a single dose nasal inhaler or an aerosol dispenser fitted with a metering valve. Where the dosage form comprises an aerosol dispenser, it will contain a propellant which can be a compressed gas e.g. air, or an organic propellant such as a fluoro-chloro-hydrocarbon or hydrofluorocarbon. Aerosol dosage forms can also take the form of pump-atomisers.

Compositions suitable for buccal or sublingual administration include tablets, lozenges and pastilles where the active ingredient is formulated with a carrier such as sugar and acacia, tragacanth, or gelatin and glycerin.

Compositions for rectal administration are conveniently in the form of suppositories containing a conventional suppository base such as cocoa butter.

Suitably, the composition is in unit dose form such as a tablet, capsule or ampoule.

The composition may for example contain from 0.1% to 100% by weight, for example from 10 to 60% by weight, of the active material, depending on the method of administration. The composition may contain from 0% to 99% by weight, for example 40% to 90% by weight, of the carrier, depending on the method of administration. The composition may contain from 0.05 mg to 2000 mg, for example from 1.0 mg to 500 mg, of the active material, depending on the method of administration. The composition may contain from 50 mg to 1000 mg, for example from 100 mg to 400 mg of the carrier, depending on the method of administration. The dose of the compound used in the treatment or prophylaxis of the aforementioned disorders will vary in the usual way with the seriousness of the disorders, the weight of the sufferer, and other similar factors. However, as a general guide suitable unit doses may be 0.05 mg to 1000 mg, more suitably 1.0 mg to 500 mg, and such unit doses may be administered more than once a day, for example two or three a day. Such therapy may extend for a number of weeks or months.

The invention provides, in a further aspect, a combination comprising a compound of formula (I) or a pharmaceutically acceptable, salt, solvate and/or derivative thereof (e.g. a combination comprising a compound of formula (I) or a pharmaceutically acceptable derivative thereof) together with a further pharmaceutically acceptable active ingredient or ingredients.

Appropriate doses will be readily appreciated by those skilled in the art.

Medical Devices

In an embodiment, compounds of the invention or pharmaceutical compositions comprising said compounds may be formulated to permit incorporation into the medical device, thus providing application of the compound or composition directly to the site to prevent or treat conditions disclosed herein.

In an embodiment, the compounds of the invention or pharmaceutical composition thereof is formulated by including it within a coating onto the medical device. There are various coatings that can be utilized such as, for example, polymer coatings that can release the compound over a prescribed time period. The compound, or a pharmaceutical composition thereof, can be embedded directly within the medical device. In some embodiments, the compound is coated onto or within the device in a delivery vehicle such as a microparticle or liposome that facilitates its release and delivery. In some embodiments, the compound or pharmaceutical composition is miscible in the coating.

In some embodiments, the medical device is a vascular implant such as a stent. Stents are utilized in medicine to prevent or eliminate vascular restrictions. The implants may be inserted into a restricted vessel whereby the restricted vessel is widened. Excessive growth of the adjacent cells following vascular implantation results in a restriction of the vessel particularly at the ends of the implants which results in reduced effectiveness of the implants. If a vascular implant is inserted into a human artery for the elimination of for example an arteriosclerotic stenosis, intimahyperplasia can occur within a year at the ends of the vascular implant and results in renewed stenosis (“restenosis”).

Accordingly, in some embodiments, the stents are coated or loaded with a composition including a compound of the invention or pharmaceutical composition thereof and optionally a targeting signal, a delivery vehicle, or a combination thereof. Many stents are commercially available or otherwise know in the art.

In some embodiments, the stent is a drug-eluting stent. Various drug eluting stents that simultaneously deliver a therapeutic substance to the treatment site while providing artificial radial support to the wall tissue are known in the art. Endoluminal devices including stents are sometimes coated on their outer surfaces with a substance such as a drug releasing agent, growth factor, or the like. Stents have also been developed having a hollow tubular structure with holes or ports cut through the sidewall to allow drug elution from a central lumen. Although the hollow nature of the stent allows the central lumen to be loaded with a drug solution that is delivered via the ports or holes in the sidewall of the stent, the hollow tubular structure may not have suitable mechanical strength to provide adequate scaffolding in the vessel.

In some embodiments, the devices are also coated or impregnated with a compound of the invention, or pharmaceutical composition thereof and one or more additional therapeutic agents, including, but not limited to, antiplatelet agents, anticoagulant agents, anti-inflammatory agents, antimicrobial agents, antimetabolic agents, additional anti-neointima agents, additional antiproliferative agents, immunomodulators, antiproliferative agents, agents that affect migration and extracellular matrix production, agents that affect platelet deposition or formation of thrombis, and agents that promote vascular healing and re-endothelialization, such as those and others described in Sousa et al. (2003) and Salu et al. (2004).

Examples of antithrombin agents include, but are not limited to, Heparin (including low molecular heparin), R-Hirudin, Hirulog, Argatroban, Efegatran, Tick anticoagulant peptide, and Ppack.

Examples of antiproliferative agents include, but are not limited to, Paclitaxel (Taxol), QP-2 Vincristin, Methotrexat, Angiopeptin, Mitomycin, BCP 678, Antisense c-myc, ABT 578, Actinomycin-D, RestenASE, 1-Chlor-deoxyadenosin, PCNA Ribozym, and Celecoxib.

Examples of anti-restenosis agents include, but are not limited to, immunomodulators such as Sirolimus (Rapamycin), Tacrolimus, Biorest, Mizoribin, Cyclosporin, Interferon-γ Ib, Leflunomid, Tranilast, Corticosteroide, Mycophenolic acid and Biphosphonate.

Examples of anti-migratory agents and extracellular matrix modulators include, but are not limited to Halofuginone, Propyl-hydroxylase-Inhibitors, C-Proteinase-Inhibitors, MMP-Inhibitors, Batimastat, Probucol.

Examples of antiplatelet agents include, but are not limited to, heparin.

Examples of wound healing agents and endothelialization promoters include vascular epithelial growth factor (“VEGF”), 17-Estradiol, Tkase-Inhibitors, BCP 671, Statins, nitric oxide (“NO”)-Donors, and endothelial progenitor cell (“EPC”)-antibodies.

Besides coronary applications, drugs and active agents may be incorporated into the stent or stent coating for other indications. For example, in urological applications, antibiotic agents may be incorporated into the stent or stent coating for the prevention of infection. In gastroenterological and urological applications, active agents may be incorporated into the stent or stent coating for the local treatment of carcinoma. It may also be advantageous to incorporate in or on the stent a contrast agent, radiopaque markers, or other additives to allow the stent to be imaged in vivo for tracking, positioning, and other purposes. Such additives could be added to the absorbable composition used to make the stent or stent coating, or absorbed into, melted onto, or sprayed onto the surface of part or all of the stent. Preferred additives for this purpose include silver, iodine and iodine labelled compounds, barium sulfate, gadolinium oxide, bismuth derivatives, zirconium dioxide, cadmium, tungsten, gold tantalum, bismuth, platinum, iridium, and rhodium. These additives may be, but are not limited to, mircro- or nano-sized particles or nano particles. Radio-opacity may be determined by fluoroscopy or by x-ray analysis.

A compound of the invention and one or more additional agents, or pharmaceutical composition thereof, can be incorporated into the stent, either by loading the compound and one or more additional agents, or pharmaceutical composition thereof into the absorbable material prior to processing, and/or coating the surface of the stent with the agent(s). The rate of release of agent may be controlled by a number of methods including varying the following the ratio of the absorbable material to the compound and one or more additional agents, or pharmaceutical composition, the molecular weight of the absorbable material, the composition of the compound and one or more additional agents, or pharmaceutical composition, the composition of the absorbable polymer, the coating thickness, the number of coating layers and their relative thicknesses, and/or the compound and one or more additional agents, or pharmaceutical composition concentration. Top coats of polymers and other materials, including absorbable polymers, may also be applied to active agent coatings to control the rate of release. For example, P4HB can be applied as a top coat on a metallic stent coated with P4HB including an active agent to retard the release of the active agent.

The invention is further exemplified by the following non-limiting examples.

Biological Examples Biological Example 1—Human CTPS1 Enzyme Inhibition

The enzyme inhibitory activities of compounds invented against the target of interest were determined using the ADP-Glo™ Max assay (Promega, UK). Assays for human CTPS1 were performed in 1× assay buffer containing 50 mM Tris, 10 mM MgCl₂, 0.01% Tween-20, pH to 8.0 accordingly. Finally, immediately before use, L-cysteine was added to the 1× assay buffer to a final concentration of 2 mM. All reagents are from Sigma-Aldrich unless specified otherwise. Human full length active C-terminal FLAG-Hiss-tag CTPS1 (UniProtKB-P17812, CTPS[1-591]-GGDYKDDDDKGGHHHHHHHH) was obtained from Proteros biostructures GmbH.

Assay Procedure

3× human CTPS1 protein was prepared in 1× assay buffer to the final working protein concentration required for the reaction. A 2 uL volume per well of 3× human CTPS1 protein was mixed with 2 uL per well of 3× test compound (compound prepared in 1× assay buffer to an appropriate final 3× compound concentration respective to the concentration response curve designed for the compounds under test) for 10 minutes at 25° C. The enzymatic reaction was then initiated by addition of a 2 uL per well volume of a pre-mixed substrate mix (UltraPure ATP from ADP-Glo™ Max kit (0.31 mM), GTP (0.034 mM), UTP (0.48 mM) and L-glutamine (0.186 mM)) and the mixture was incubated for an appropriate amount of time within the determined linear phase of the reaction at 25° C. under sealed plate conditions with constant agitation at 500 revolutions per minute (rpm). ADP-Glo™ Max reagent was added for 60 minutes (6 uL per well) and subsequently ADP-Glo™ Max development reagent was added for 60 minutes (12 uL per well) prior to signal detection in a microplate reader (EnVision@ Multilabel Reader, Perkin Elmer).

Following each reagent addition over the course of the assay, assay plates were pulse centrifuged for 30 seconds at 500 rpm.

In all cases, the enzyme converts ATP to ADP and the ADP-Glo™ Max reagent subsequently depletes any remaining endogenous ATP in the reaction system. The ADP-Glo™ Max detection reagent converts the ADP that has been enzymatically produced back into ATP and using ATP as a substrate together with luciferin for the enzyme luciferase, light is generated which produces a detectable luminescence. The luminescent signal measured is directly proportional to the amount of ADP produced by the enzyme reaction and a reduction in this signal upon compound treatment demonstrates enzyme inhibition. The percentage inhibition produced by each concentration of compound was calculated using the equation shown below:

${\%{Inhibition}} = {1 - {\frac{\left( {{Mean}_{Min} - {Mean}_{Inh}} \right)}{\left( {{Mean}_{Min} - {Mean}_{{Max})}} \right.} \times 100}}$

Percentage inhibition was then plotted against compound concentration, and the 50% inhibitory concentration (IC₅₀) was determined from the resultant concentration-response curve.

The data for all compounds tested are presented below.

Biological Example 2—RapidFire/MS-based Enzyme Selectivity Assays

Human CTPS1 Versus CTPS2 Selectivity Assessment by RapidFire/MS Analysis.

The enzyme inhibitory activities against each target isoform of interest may be determined for the compounds of the invention using an optimised RapidFire high-throughput mass spectrometry (RF/MS) assay format. RF/MS assays for both human CTPS1 and CTPS2 may be performed in assay buffer consisting of 50 mM HEPES (Merck), 20 mM MgCl₂, 5 mM KCl, 1 mM DTT, 0.01% Tween-20, pH to 8.0 accordingly. Human full-length active C-terminal FLAG-His-tag CTPS1 (UniProtKB-P17812, CTPS[1-591]-GGDYKDDDDKGGHHHHHHHH) may be obtained from Proteros biostructures GmbH. Human full length active C-terminal FLAG-His-Avi tagged CTPS2 (UniProtKB-Q9NRF8, CTPS2 [1-586]-DYKDDDDKHHHHHHGLNDIFEAQKIEWHE) may be obtained from Harker Bio.

Assay Procedure

Human CTPS (1 or 2) protein may be prepared in 1× assay buffer to the final working protein concentration required for the reaction. A 2 uL volume per well of 2×CTPS (1 or 2) protein may be mixed with 40 nL of compound using acoustic (ECHO) delivery and incubated for 10 minutes at 25° C. Each isoform enzymatic reaction may be subsequently initiated by addition of 2 uL per well of a 2× substrate mix in assay buffer. For hCTPS1: ATP (0.3 mM), UTP (0.2 mM), GTP (0.07 mM) and L-glutamine (0.1 mM). For hCTPS2: ATP (0.1 mM), UTP (0.04 mM), GTP (0.03 mM) and L-glutamine (0.1 mM). Each mixture may be incubated for an appropriate amount of time per isoform within the determined linear phase of the reaction at 25° C. A 60 uL volume of stop solution (1% formic acid with 0.5 uM ¹³C₉-¹⁵N₃-CTP in H₂O) may be added and the plate immediately heat-sealed and centrifuged for 10 minutes at 4,000 rpm. Following centrifugation, plates may be loaded onto the Agilent RapidFire microfluidic solid phase extraction system coupled to an API4000 triple quadrupole mass spectrometer (RF/MS) for analysis.

In all cases, the enzyme converts UTP to CTP. Highly specific and sensitive multiple reaction monitoring (MRM) MS methods may be optimised for the detection of the enzymatic reaction product, CTP, and the stable isotope labelled product standard ¹³C₉-¹⁵N₃-CTP. Readout for data analysis may be calculated as the ratio between the peak area of the product CTP and the internal standard ¹³C₉-¹⁵N₃-CTP. For data reporting, the following equation may be used:

$R = \frac{P}{IS}$

-   -   (R=ratio/readout, P=product signal area, IS=internal standard         signal area)

For each screening plate, the means of the negative (DMSO) and positive control values may be used for the calculation of the respective assay window (S/B) and Z′ values. The median of the respective control values may be used for calculation of percent inhibition according to the following equation:

$I = {\frac{R_{neg} - R_{sample}}{\left\lbrack {R_{neg} - R_{pos}} \right\rbrack}\%}$

-   -   (I=Inhibition, R_(neg)=median of negative control readout         values, R_(pos)=median of positive control readout values,         R_(sample)=sample readout value)

Percentage inhibition may be then plotted against compound concentration, and the 50% inhibitory concentration (IC₅₀) may be determined from the resultant concentration-response curve.

Fold selectivity between CTPS1 and CTPS2 may be subsequently calculated according to the following equation:

${{Fold}{selectivity}} = \frac{{CTPS}2{IC}_{50}}{{CTPS}1{IC}_{50}}$
